I want the best and most stable water condition for my tank I have 20lbs of live rock and 500gph of flow in my tank right now. I plan on having all sorts of corals and 1-2 fish. My ? is should I add a skimmer or a refuge? I don't real want to run a sump. Less pumps the butter my kids room looks like a controle panel already. Or do you think my tank should be fine? Thanks
